Analogous to [1]}, [2]}, we also utilize the coarse-to-fine approach through a pyramidal processing as illustrated in Fig. REF . Note that although it was claimed that utilizing the high-level features has a negative effect on performance [3]}, e.g., conv5\(\_\) x, numerous recent works [4]}, [5]}, [6]}, [1]} in both semantic matching and few-shot segmentation task demonstrated that leveraging multi-level features results in performance boost by large margin. Motivated by this, we also use pyramidal hypercorrelation.
